Your daughter is young to be going into puberty.This is called precocious puberty.She can be seen by her regular paediatrician and hormone tests may be done if thought necessary. Her hands feeling 'dead' is probably not linked but may be due to pressure on a nerve or the blood supply to her hands.This may be due to the presence of an extra rib known as a cervical rib among the possible causes.Please mention this to the paeditrician.
